Claim of US Patent No. 10,893,537

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:detecting first downlink control information transmitted from a specific cell;
based on the first downlink control information being detected, detecting second downlink control information included in a shortened downlink control channel, based on resource information on the shortened downlink control channel included in the first downlink control information; and
based on the first downlink control information being not detected, changing at least one of a shortened downlink data channel, a shortened uplink data channel, and a transmission and reception timing of ACK/NACK signals, which are previously configured based on capability of the UE,
wherein changing the at least one of the shortened downlink data channel, the shortened uplink data channel, and the transmission and reception timing of the ACK/NACK signals comprises:
measuring the capability of the UE and reporting the capability to the specific cell;
receiving information for at least one of the shortened downlink data channel, the shortened uplink data channel, and the transmission and reception timing of the ACK/NACK signals, which are determined by the specific cell, based on the capability of the UE; and
changing at least one of the shortened downlink data channel, the shortened uplink data channel, and the transmission and reception timing of the ACK/NACK signals, based on the received information.
